Other features found on his property include 3% of Indiana’s old growth forest, as well as many acres of reforested woods. An 1833 dairy barn that acts as our Nature Center, filled with exhibits on regional flora and fauna. There's also the Hayes Museum, where you can learn about the Arboretum's rich history. Throughout the Arboretum you can find ponds, fields, wetlands, and even an Indian Mound. Hayes Arboretum is open free of charge to the public.
